rapid hardening

The results show that trace Cr can enhance Cu Zn alloy hardness and recrystallized temperature in the way of precipitation hardening. Rapid heat rolling and quenching can hold the effects of working hardening, and thermomechanical treatment can develop structure hardening as well.

结果表明：微量Cr能提高Cu Zn合金硬度和再结晶温度，Cr对合金性能的影响是通过沉淀强化来实现的，快速热轧淬火具有保留加工强化的效果，形变热处理还产生了组织强化。
